मानव ह्रदय की क्रियाविधि :हृदय ही शरीर के विभिन्न भागों से रुधिर को ग्रहण भी करता हैं। हृदय शरीर में रुधिर को पम्प करने का कार्य करता है। इस कार्य के लिए हृदय हर समय सिकुड़ता तथा शिथिल होता रहता है। हृदय के सिकुड़ने को प्रकुंचन (सिस्टोल) तथा शिथिल होने को अनुशिथिलन (डायस्टोल) कहते हैं।

GreenExplanation:When a copper vessel is exposed to moist air for a long time it develops a green layer on its surface. Copper CORRODES by oxidation in which it REACTS with oxygen in the air to form copper oxide. Copper oxide then combines with CARBON dioxide to make copper carbonate, which GIVES it a green colour. This process is called corrosion of copper.The green material is a mixture of copper hydroxide (Cu(OH)2) and copper carbonate (CuCO3). The following is the reaction:2Cu(s)+H2​O(g)+CO2​+O2​→Cu(OH)2​+CuCO3​(s)Copper(II) carbonate is a blue-green compound.Hence, option B is correct.

If any luggage kept on the roof of the bus is not tied with a rope, then it TENDS to move forward due to its INERTIA. In this PROCESS, it could fall off the bus. Therfore, it is ADVISED to TIE any luggage kept on the roof of a bus with a rope.

The producers, as autotrophs are ALSO known, begin food chains which feed all life. Heterotrophs cannot make their own food, so they must EAT or ABSORB it. For this reason, heterotrophs are also known as CONSUMERS. Consumers INCLUDE all animals and fungi and many protists and bacteria

The arrangement and DISTRIBUTION of ELECTRONS in different orbits was given by BOHR and Bury. The arrangement of electrons in different shells and sub-shells is known as the electronic configuration of a PARTICULAR element. ... For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons.

tion:When a piece of Potassium permanganate (KMnO₄) is added to or placed at the bottom of a BEAKER which contains cold water, then the water turns into a purple COLOURED solution.1. The colour of the solution is dark purple after 5 mins of the addition of the KMnO₄ piece to the water. This is due to diffusion of the KMnO₄ particles in the water.2. After several hours, the colour of the solution may change to a purple shade that is lighter than the initial colour.3. This is because the solution of water and KMnO₄ is made up of very tiny particles which get DISPERSED and spread amongst themselves. When the KMnO₄ particles are together, they give a dark purple colour. As they get dispersed in the water, the purple particles will spread making the solution lighter in colour.4. The 2 processes that are taking place in this experiment are diffusion and dispersion.

tion:The extraction kinetics behaviour of lutein from Marigold flower petals and simultaneous alkali hydrolysis has been studied. Extraction was carried out by varying following OPERATING conditions: type of organic solvent, temperature, RATIO liquid: MATERIAL, concentration of alkali SOLUTION, and particle size of plant material. Experimental extraction curves were analysed with a mathematical model derived from Fick's second law. The extraction of lutein appeared to be governed by slow and fast diffusion PROCESSES. Results showed that the intra-particle diffusion was the rate-governing step of the extraction process, and that the chosen model gives very good approximation of experimental data.

tion:In an electric circuit, a battery and a bulb have been connected, and the battery consists of two cells of EQUAL potential difference, if the bulb is not glowing, which test will you perform?This would be a troubleshooting flow in ORDER from the easiest and most obvious check to ones requiring test gear.Visually check to make sure the batteries are connected properly; in series and not opposition. Series would be -+-+ so the voltage is additive. With a ++ or - - connection, resultant voltage will be zero.Using a voltmeter, check voltage at bulb connection or socket. This will determine if POWER is available to the bulb.If steps 1 & 2 are GOOD, remove the bulb and check for resistance using an ohmmeter. Open or extremely high resistance indicates EITHER an open bulb or a failure.
